The 2SK2467 is an N-channel silicon junction field-effect transistor (JFET) manufactured by Toshiba Semiconductor and Storage. It's primarily intended for use in audio amplifiers and impedance conversion circuits where low noise and high input impedance are critical. The JFET provides a linear amplification characteristic, contributing to excellent signal fidelity in audio applications.
Applications:
